RAILROAD-CAR COUPLING.

Specication of Letters Patent No. 23,282, dated March 15, 1859'.

To all wwm-t may concern: Y

Be it known that We, NOAH H. W'ENT- woR'rH and MARTIN L. AMES, of thetown or" Somersworth, in the county of Stafford and State of NewHampshire, have `invented a neiv and useful mprovement in Car-Couplings;and We do hereinT dee-lare that the following is a full and exactdescription of the same, reference being had to the accompanyingdrawings and to the letters and marks thereon.

Of the drawings forming part of this specication, Figure 1, representsthe conpling in the condition for holding the cars together; Fig. 2, thecondition when ready for being separated; and Fig. 3, shovvs one of theparts of the coupling only with the latch or catch inclined downward bythe iorce of the spring.

Each part of this coupling is made up of a frame or case (n), having alatch or catch (Z2), a lever (c), a shaft (cl) to which is affixed thelatch andthe lever, a crankarm (c) for operating the shaft (f) and twocams g, g), the one being under the latch and the other (9') being underthe lever, and a spring (fr) for forcing the latch downward and holdingit in position when the parte are coupled.

It will he seen that when both of` the parte of the coupling are aliixedto cars, the latch of the one part will, by the proper movement of thecar being given, readiljT pass over the bar of the other part of y thecoupling and catch and be held in its connecting position, provided thelever of the other part is depressed, and thus the catches of both partsof the coupling will hold the one to the other. Vvhenever it is desiredto unconple, turning the crank-arm (e) will elevate the cams (g, g), theone cam acting directly on the latch or catch and the other cam actingindirectly through the lever. Under this arrangement both shafts becomethe means of operating on both latches, and `both levers act as guidesto the latches as Well as levers. Each crank-arm (e) can he actuatedindependently or several of them may be operated conjointly by anyconvenient means for that purpose. This arrangement of the latches andlevers With the cams and shafts makes a very sure and steady coupling.

Having thus set ont our invention vvhat We claim as newY and desire tosecure by Letters Patent is,

Combining with each latch or catch a lever as herein described, andproviding the latch and lever when thus combined With the cams and theirshafts and crank-arms for actuating them, as and for the purposes setforth.
